RTC_IER field descriptions
Field Description
31–19
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
18–16
TSIC
Timer Seconds Interrupt Configuration
Configures the frequency of the RTC Seconds interrupt and the RTC_CLKOUT prescaler output. This field
should only be altered when TSIE is clear.
000 1 Hz.
001 2 Hz.
010 4 Hz.
011 8 Hz.
100 16 Hz.
101 32 Hz.
110 64 Hz.
111 128 Hz.
15–8
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
7
WPON
Wakeup Pin On
The wakeup pin is optional and not available on all devices. Whenever the wakeup pin is enabled and this
bit is set, the wakeup pin will assert.
0 No effect.
1 If the wakeup pin is enabled, then the wakeup pin will assert.
6–5
Reserved
This field is reserved.
4
TSIE
Time Seconds Interrupt Enable
The seconds interrupt is an edge-sensitive interrupt with a dedicated interrupt vector. It is generated once
a second and requires no software overhead (there is no corresponding status flag to clear).
0 Seconds interrupt is disabled.
1 Seconds interrupt is enabled.
3
Reserved
This field is reserved.
2
TAIE
Time Alarm Interrupt Enable
0 Time alarm flag does not generate an interrupt.
1 Time alarm flag does generate an interrupt.
1
TOIE
Time Overflow Interrupt Enable
0 Time overflow flag does not generate an interrupt.
1 Time overflow flag does generate an interrupt.
0
TIIE
Time Invalid Interrupt Enable
0 Time invalid flag does not generate an interrupt.
1 Time invalid flag does generate an interrupt.
